Description

The proposed technical solution relates to the field of disassembly of electromagnetic relays for the purpose of their disposal using stamps and can be used to extrude a bronze stop from a steel anchor of a 3rd generation electromagnetic relay of railway automation and telemechanics.

It is widely known that stamps of various designs are used, including for dividing operations. (Guide to the designer of stamps: Sheet stamping / Under the general editorship of L.I. Rudman - M .: Engineering, 1988 - 496 p. 48-168) As a drawback of the presented designs of the stamps, their impossibility to use when disassembling electromagnetic relays when it is required to perform pressing operations on the finished product as a whole or on its individual nodes. For each separation operation, when disassembling electromagnetic relays for the purpose of their disposal, it is structurally necessary to develop a separate stamp, taking into account the features of the operation performed, the design of the part, assembly and relay device as a whole.

The objective of the proposed technical solution is the disposal of elements of automation and telemechanics of railway transport.

When solving this problem, a technical result is achieved, consisting in increasing the performance of disassembling electromagnetic relays, eliminating manual labor.

The specified technical result is achieved by a stamp for extruding the bronze stop from the steel armature of the electromagnetic relay, characterized in that it has a rear arrangement of guide columns and bushings, contains an upper movable plate with a punch holder mounted on it, a gasket located between the upper plate and punch holder, a punch fixed in the punch holder , the punch is made in the form of two cylinders and a cone coaxially interconnected, a fixed lower plate mounted on a base plate, The matrix mounted on the bottom plate, the matrix is made in the form of a plate, on the working surface of which is fixed a latch and a bar for positioning the steel anchor, the matrix has a working hole, left and right, the front protective screens are fixedly mounted on the upper plate, the main screen is movably fixed to bottom plate. In addition, a shank for connecting to the drive is fixed to the top plate, the top plate and punch holder are connected by pins and screws, the matrix and the bottom plate are connected by pins and screws.

The claimed technical solution is illustrated by drawings, which show: in FIG. 1 is a plan view of a stamp along section AA of FIG. 2, in FIG. 2 - lower part of the stamp, top view, in FIG. 3 the upper part of the stamp, top view, in FIG. 4 is a plan view of a stamp along section BB of FIG. 1, in FIG. 5 is a matrix, a top view, in FIG. 6 - latch, in FIG. 7 - a punch, on fig. 8 - the main screen.

The stamp for extruding the bronze stop from the steel armature of the electromagnetic relay consists of rear-mounted guide columns 1 and bushings 2, contains an upper movable plate 3 with a punch holder 4 fixed thereon, a gasket 5 located between the upper plate 3 and the punch holder 4. Upper plate 3 and punch holder 4 connected by pins 6 and screws 6.1. The punch 7 is made in the form of two cylinders 7.1 and 7.2 coaxially interconnected and a cone 7.3, fixed in the punch holder 4. Left 8.1 and right 8.2, front 9.1 and 9.2 protective shields are fixedly mounted on the top plate 3. Fixed bottom plate 10 is mounted on the base plate 11. The matrix 12 is mounted on the bottom plate 10 with pins 10.1 and screws 10.2. The matrix 12 is made in the form of a plate with a working hole 12.1, a latch 13 and a strap 14 are fixed on the working surface for positioning the steel anchor 15. The main screen 16 is movably mounted on the bottom plate 10 with the possibility of rotation through an angle of 90 ° relative to the axis 16.1. On the upper plate 3, a shank 17 is fixed for connection to the drive.

The stamp works as follows. To extrude the bronze stop from the steel armature 15 of the electromagnetic relay, the punch 7 with the top plate 3 is pulled upward relative to the matrix 12. The main screen 16 is folded out, an anchor 15 is mounted on the latch 13 under the bar 14, the screen 16 is returned to its original position. During the working stroke of the punch 7 with the plate 3, the bronze stop is pressed out of the steel armature 15 of the electromagnetic relay. The proposed technical solution allows you to quickly, with minimal manual labor costs, to separate the bronze emphasis of the steel armature of the electromagnetic relay. A stamp for extruding the bronze stop from the steel armature of the electromagnetic relay undergoes production tests at the Kamyshlovsky Electrical Plant.
